While the Silicon Valley-based incubator has overseen the development of several successful companies like, Airbnb, Docker, and Instacart, Dropbox will be the first within the Y Combinator program to go public.

Led by Sam Altman and founded by Paul Graham, Robert Morris, Jessica Livingston, and Trevor Blackwell in 2005, Y Combinator quickly rose to prominence as a program for young startups to gain a network of investors and advisors, in addition to seed funding, in exchange for the incubator taking an equity stake. In December, Y Combinator announced plans for a development program for later-stage startups.
